FIELD OF THE INVENTION

The present invention is related to a phosphorylase, a method for reacting a glucosyl monosaccharide and alpha-D-glucose 1-phosphate, a method for converting glucose and alpha-D-glucose 1-phosphate into trehalose and inorganic phosphate, and the use of the phosphorylase for producing trehalose.

BACKGROUND OF THE INVENTION

Phosphorylases are enzymes which catalyze the addition of a phosphate group from an inorganic phosphate to an acceptor molecule. Phosphorylases which catalyse the reversible phosphorolytic cleavage of trehalose are known in the art and referred to as trehalose phosphorylases. Trehalose phosphorylases can be a distinguished based on the mechanism underlying the reaction catalysed by them.

A first group of trehalose phosphorylases catalyzes phosphorolytic cleavage of trehalose with net retention of the anomeric configuration using inorganic phosphate as a glucosyl acceptor into glucose and alpha-D-glucose 1-phosphate (aG1P) and are therefore classified as retaining phosphorylases. Trehalose phosphorylases of such first group have been assigned EC number EC 2.4.1.231 by the International Union of Biochemistry and Molecular Biology and have been functionally characterized from various eukaryotic fungi.

A second group of trehalose phosphorylases are inverting trehalose phosphorylases to which EC number EC 2.4.1.64 has been assigned and which are catalyzing phosphorolytic cleavage of trehalose with inversion of configuration into glucose and beta-D-glucose 1-phosphate. These phosphorylases thus have a reaction mechanism different from EC 2.4.1.231 trehalose phosphorylases.

Specifically this invention relates to certain phosphorylases of EC number EC 2.4.1.231, that are capable of converting, among other reactions, glucose and alpha-D-glucose-1 phosphate (“aG1P”) to trehalose, or of phosphorolytic cleavage of trehalose to glucose and aG1P in the presence of inorganic phosphate.

The industrial use of trehalose phosphorylases results from the fact that the reaction underlying their biochemical characterization, i.e. catalyzing phosphorolytic cleavage of trehalose, is reversible. Because of this, trehalose phosporylases are particularly useful for catalyzing the conversion of glucose and aG1P to trehalose and inorganic phosphate.

The reaction that is catalyzed by trehalose phosphorylases is reversible (equilibrium reaction) and may undergo substrate or product inhibition, depending on the specific direction of the reaction. In order to obtain industrially relevant amounts of a desired product, trehalose phosphorylases are required that catalyze the conversion of substrates with high specific activity. In addition, other kinetic factors of the trehalose phosphorylases, such as substrate selectivity and K_(M) may play an important role for product yields. Other relevant aspects may include but are not limited to regioselectivity, inhibition by other factors (e.g. crude extract components, substrate contaminants or side products), and recombinant soluble expression in suitable hosts.

A major shortcoming of wild type trehalose phosphorylases is the rapid loss of enzyme activity in solution even at moderate temperatures between 25° C. and 40° C., which significantly limits their application. For industrial applications, high stability over several days at temperatures above 30° C., or even better above 40° C. is desirable. Long reaction times with thermally instable enzymes requires larger amounts of enzyme over process time, often realized by repeated addition of enzyme throughout the process. For example, trehalose phosphorylase from Pleurotus ostreatus shows a half-life of approximately 1.3 h at 25° C. and of 3 min at approximately 41° C. (Schwarz et al., J Biotechnol 129, 140-150 (2007), Han et al., Protein Expression and Purification 30, 194-202 (2003)). The trehalose phosphorylases from Schizophyllum commune and Grifola frondosa are slightly more stable with half-lives of 4.8 h at 30° C. and of 1 h at 37° C., respectively (Schwarz et al., J Biotechnol 129, 140-150 (2007)).

Various strategies were applied in the art to address such shortcomings. For example, addition of trehalose, glycerol and polyethylene glycol (PEG) was shown to increase trehalose phosphorylases stability (Klimacek et al., Biotechnology Techniques 13: 243-248, 1999, Eis et al., Biochem J 341, 385-393 (1999), Schwarz et al. J Biotechnol 129, 140-150 (2007)). The best stabilization was achieved by adding 20% PEG 4000, which resulted in half-lives of trehalose phosphorylase from Schizophyllum commune at 30° C., 40° C. and 50° C. of 4.5 days, 2.2 hours and 6 min, respectively (Klimacek et al., Biotechnology Techniques 13: 243-248, 1999, Eis et al., Biochem J 341, 385-393 (1999)). While the addition of PEG 4000 improved the stability of the enzyme, such improvement is still insufficient for applications at or above 40° C. and process times of several hours to several days. The presence of PEG 4000 may furthermore interfere with industrial scale cost structure and down-stream processing requirements for the products obtained by the enzymatic reaction.

Half-life of trehalose phosphorylases from Schizophyllum commune could also be improved by immobilization to 22 days, 3.3 days and 2 hours at 30° C., 40° C. and 50° C., respectively (Klimacek et al., Biotechnology Techniques 13: 243-248, 1999). Immobilization, however, results in higher enzyme production costs due to expensive carrier and manufacturing costs, and is efficient in terms of industrial applicability only if the enzyme can be recovered and reused for multiple cycles. Additionally, immobilization limits process and down-stream processing options for products of the enzymatic reaction.

It is therefore not surprising that synthesis reactions employing trehalose phosphorylases are conducted at temperatures ranging from 25° C. to 35° C. (Schwarz et al., J of Biotechnology 129 140-150 (2007), Saito et al., Appl Microbiol Biotechnol 50:193-198 (1998), Saito et al. Appl Microbiol Biotechnol 64: 4340-4345 (1998)).

A further approach for improving performance of enzymes and their suitability for use in industrial processes is enzyme engineering. This technique involves developing variants of a starting enzyme with improved properties (for review, see, for example, S. Lutz, U. T. Bornscheuer, Protein Engineering Handbook, Wiley VCH, Weinheim, 2009). Among others, phosphorylases were improved by enzyme engineering. For example, US 2013-0029384 discloses variants of a sucrose phosphorylase belonging to glycosyl hydrolase family 13 having improved thermal stability. Variants of trehalose phosphorylase of EC number EC 2.4.1.231 have so far been limited to variants for elucidation of the reaction mechanism of said trehalose phosphorylase. Based on such variants, Goedl et al. (Biochem J 397; 491-500; 2006) discovered that substitutions at amino acid positions D379, H403, R507 and K512 of trehalose phosphorylase from Shizophyllum commune led to a reduction in activity. The variants having one of the following single mutations D379N, H403A, R507A and K512A showed reduced activity for trehalose phosphorolysis. Goedl et al. (FEBS J 275; 903-913, 2008) more specifically found that mutations R507A and K512A of trehalose phosphorylase from Shizophyllum commune had an impact on catalytic efficiency of trehalose phosphorylase of the wild type (kcat/K_(M)).

As the wild type trehalose phosphorylases available from the prior art are not satisfactory in every respect, and attempts to efficiently improve the industrial applicability of trehalose phosphorylases, as described in the art were not successful, there is a need for trehalose phosphorylases which are advantageous compared to wild type trehalose phosphorylases, in particular with respect to process stability at high temperatures for the industrial production of trehalose.

Accordingly, the problem underlying the present invention is the provision of a trehalose phosphorylase which is suitable for use in industrial production of trehalose.

A further problem underlying the present invention is the provision of a trehalose phosphorylase which is thermally stable and shows a residual activity ranging from 30% to 90% or from 55% to 100% after incubation at 52° C. for 15 minutes without the necessity of immobilizing the enzyme or adding any stabilizing agent (e.g., PEG or glycerol) apart from sucrose.

Another problem underlying the present invention is the provision of a trehalose phosphorylase which is thermally stable and shows a half-life at 45° C. from 3 hours to 9 days or more without the necessity of immobilizing the enzyme or adding any stabilizing agent (e.g., PEG or glycerol) apart from sucrose.

Another problem underlying the present invention is the provision of a trehalose phosphorylase which has a 100/500-ratio ranging between 0.65 and 1.0.

A still further problem is the provision of means which allow converting glucose and alpha-D-glucose 1-phosphate into trehalose and inorganic phosphate.

It will be understood that the trehalose phosphorylase described herein in its various aspects and embodiments may also be referred to as the trehalose phosphorylase of the present invention.

The present invention is based on the surprising finding that trehalose phosphorylase of EC number EC 2.4.1.231, which is also referred to as “TP”, may be improved by enzyme engineering. As a starting point for such enzyme engineering trehalose phosphorylase having an amino acid sequence according to SEQ ID NO: 1 was used. Said trehalose phosphorylase having an amino acid sequence according to SEQ ID NO: 1 may be prepared from Shizophyllum commune which was characterized by Eis et al. (FEBS Letters 440, 440-443 (1998)). UniProt: D8PWQ7 (GenBank: EFJ00254.1) discloses the wild type protein sequence of an individual Schizophyllum commune isolate H4-8 (99.1% identity). The sequence deviates from SEQ ID NO: 1 in seven positions of SEQ ID NO: 1, wherein the isolate H4-8 carries a lysine amino acid residue in the position homologous to position 10 of SEQ ID NO: 1, a serine amino acid residue in the position homologous to position 32 of SEQ ID NO: 1, a valine amino acid residue in the position homologous to position 374 of SEQ ID NO: 1, a glutamic acid amino acid residue in the position homologous to position 535 of SEQ ID NO: 1, a proline amino acid residue in the position homologous to position 536 of SEQ ID NO: 1, an isoleucine amino acid residue in the position homologous to position 616 of SEQ ID NO: land a valine amino acid residue in the position homologous to position 649 of SEQ ID NO: 1. UniProt: A0A151VW19 (GenBank: KYQ39707.1) discloses the wild type protein sequence of a trehalose phosphorylase from the organism Hypsizygus marmoreus, which is to 77.9% identical to SEQ ID NO: 1. Besides Schizophyllum commune TP, other TPs from fungal origin have been described, e.g. Lentinus sajor-caju (73.2% homology), Pleurotus ostreatus (75.8% homology), or Grifola frondosa (76.7% homology). For Grifola frondosa, protein sequences derived from different isolates have been described, amongst them the sequences SEQ ID NO: 160 (UniProtKB/Swiss-Prot: Accession No: 075003.1) and SEQ ID NO: 81 (Genbank Accession No: ADM15725.1).

Further embodiments of the trehalose phosphorylase of the present invention are those where the one or more additional amino acid position is selected from a more limited group, including those more limited groups of additional amino acid positions specifically disclosed herein. It is within the present invention that a trehalose phosphorylase comprises an amino acid substitution at one of these pairs of two amino acid positions of SEQ ID NO: 1 and at one of said additional amino acid sequences. In accordance therewith, the trehalose phosphorylase of the present invention is, each in an embodiment, a trehalose phosphorylase having an amino acid substitution at at least three amino acid positions, namely at the pair of two amino acid position and at one of said additional amino acid positions of SEQ ID NO: 1, a trehalose phosphorylase having an amino acid substitution at at least four amino acid positions, namely at the pair of two amino acid position and at two of said additional amino acid positions of SEQ ID NO: 1, a trehalose phosphorylase having an amino acid substitution at at least five amino acid positions, namely at the pair of two amino acid position and at three of said additional amino acid positions of SEQ ID NO: 1, or a trehalose phosphorylase having an amino acid substitution at at least six amino acid positions, namely at the pair of two amino acid position and at four of said additional amino acid positions of SEQ ID NO: 1.

Further embodiments of the trehalose phosphorylase of the present invention are those where the one or more still further amino acid position is selected from a more limited group, including those more limited groups of additional amino acid positions specifically disclosed herein.

As to specific substitutions disclosed herein it is to be noted that in accordance with common practice in the field of amino acid substitutions the substitution refers to the number of the amino acid position where a substitution is made, with the left number being flanked on both sides by the indication of an amino acid residue with the amino acid residue on the left side being the amino acid residue as present in the non-substituted amino acid sequence and the amino acid residue on the right side being the amino acid residue as present in the substituted amino acid sequence. Accordingly and for illustrative purposes only, substitution V10R indicated that at amino acid position 10 the valine reside is replaced by arginine.

It is within the present invention that any of the mutations at an amino acid positions of SEQ ID NO: 1 as disclosed herein is one which results, either alone or in any combination, in a protein which is still active as a trehalose phosphorylase, more specifically as a trehalose phosphorylase in accordance with EC 2.4.1.213. Preferably, any of said mutations results, either alone or in any combination, in a trehalose phosphorylase of EC number EC 2.4.1.213 having at least one of characteristics (A), (B), (C), (D) and (E), or any combination of such characteristics, as disclosed herein.

It will be understood that in connection with the trehalose phosphorylase of the present invention apart from the substitutions specifically discloses herein, preferably the substitutions at the amino acid positions of SEQ ID NO:1 disclosed herein, further and/or different substitution may be made. Preferably, such further substitutions are made at positions different from amino acid positions D379, H403, R507 and K512, each of SEQ ID NO: 1, which positions are described to be essential for proper reaction catalysis.

It is known how the identity and homology, respectively, of a polymer of amino acid residues is determined. Homology is preferably calculated as identity using BLASTP (see, for example, Stephen F. Altschul, Thomas L. Madden, Alejandro A. Schaffer, Jinghui Zhang, Zheng Zhang, Webb Miller, and David J. Lipman (1997) “Gapped BLAST and PSI-BLAST: a new generation of protein database search programs”, Nucleic Acids Res. 25:3389-3402; or Stephen F. Altschul, John C. Wootton, E. Michael Gertz, Richa Agarwala, Aleksandr Morgulis, Alejandro A. Schaffer, and Yi-Kuo Yu (2005) “Protein database searches using compositionally adjusted substitution matrices.” FEBS J. 272:5101-5109).

It is within the present invention that any activity and any activity of the trehalose phosphorylase is in an embodiment a catalytic activity.

Assay I: Phosphorolytic activity was routinely assayed at 30° C. using a continuous coupled assay in which the aG1P produced from trehalose is converted to glucose-6-phosphate by phosphoglucomutase. Glucose-6-phosphate and NADP is converted to 6-phospho-gluconate and NADPH by glucose 6-phosphate dehydrogenase. The detection is based on measuring the absorbance of NADPH at 340 nm. The assay solution contained: 75 mM potassium phosphate buffer pH 7, 2.5 mM NADP, 10 μM glucose 1,6-bisphosphate, 10 mM MgCl2, 225 mM trehalose, 3 U/mL phosphoglucomutase and 3.4 U/mL glucose 6-phosphate dehydrogenase.

Assay II: Synthetic activity was routinely assayed at 40° C. using the following conditions: 50 mM sodium MES buffer pH 7, 100 mM aG1P and 100 or 500 mM glucose concentrations as given. Reaction progress was determined discontinuously by measuring liberated phosphate with an assay based on the complex formation with molybdate under acidic conditions. The molybdate complex is reduced by ferrous sulfate and yields a blue color, which is analyzed photometrically at 750 nm. For the analysis 250 μL of sample are mixed with 250 μL 0.5 M HCl and 500 μL molybdate-reagent (73.2 g/L Fe(II)SO4*7H2O and 10 g/L ammonium molybdate*4H2O in 3.5% sulfuric acid). After incubation at RT for 15-30 min, absorbance is measured at 750 nm. The amount of inorganic phosphate in the sample is quantified using external standards.

Definition S/P-ratio: For the purpose of this invention, the S/P-ratio is defined as the ratio between phosphorolysis activity and synthesis activity measured by Assay 1 and Assay 2, respectively, using 500 mM glucose as described in the examples.

Definition 100/500-ratio: For the purpose of this invention, the 100/500-ratio is the ratio between activity of a TP variant using 100 mM glucose and activity of a TP variant using 500 mM glucose with 100 mM aG1P, respectively, according to Assay 2. An increase in 100/500-ratio of an enzyme variant compared to the wild-type enzyme is indicative of a decreased KM-value for glucose.

In an embodiment, if not indicated to the contrary any activity, enzymatic activity, phosphorolysis activity and synthesis activity displayed or to be displayed by the polypeptide and, preferably any trehalose phosphorylase, of the present invention is defined and, respectively, determined by the methods and assays, respectively, disclosed herein.

EXAMPLES Example 1: General Methods

Cloning of the wild type TP: The trehalose phosphorylase gene from S. commune was codon-optimized for expression in E. coli and synthesized by Eurofins MWG Operon. The gene was cloned into the expression vector pLElA17 (derivative of pRSF-1b, Novagen). The resulting plasmids were used for transformation of E. coli BL21(DE3) cells.

Molecular biology methods: Mutants of the TP enzymes were created by standard site-directed mutagenesis technologies as known in the state of the art.

Expression of recombinant TPs: Recombinant TPs were routinely expressed by inoculating Medium I (4.6 g/L yeast extract, 9.3 g/L peptone, 25 mM Na2HPO4*12H2O, 25 mM KH2PO4, 50 mM NH4Cl₂, Na2SO4, 5 g/L glycerol, 0.5 g/L glucose*1H2O, 2 mM MgSO4, 50 μg/mL kanamycin) with a fresh overnight culture. Cultures were grown at 37° C. up to an optical density at 600 nm of 0.6-0.8. Cultures were induced with 0.1 mM IPTG final concentration. Expression was at 24-25° C. overnight.

Preparation of TP enzyme preparations: Preparation of cell free extract was done using procedures well known as described elsewhere. Cells were harvested by centrifugation and suspended in a buffer containing 50 mM potassium phosphate-buffer pH 7, 2 mM MgCl2, 0.5 mg/mL lysozyme and 20 U/mL nuclease. 1 M sucrose was at times added as a stabilizing agent. Cell disruption was achieved by sonication or repeated freeze/thaw cycles. Cell free extract containing soluble enzyme was separated from the debris by centrifugation.

Activity measurements: Activity of trehalose phosphorylase can be determined in both the direction of trehalose cleavage (phosphorolytic activity) and synthesis (synthetic activity) as described in Assay I and Assay II:

Assay I: Phosphorolytic activity was routinely assayed at 30° C. using a continuous coupled assay in which the aG1P produced from trehalose is converted to glucose-6-phosphate by phosphoglucomutase. Glucose-6-phosphate and NADP is converted to 6-phospho-gluconate and NADPH by glucose 6-phosphate dehydrogenase. The detection is based on measuring the absorbance of NADPH at 340 nm. The assay solution contained: 75 mM potassium phosphate buffer pH 7, 2.5 mM NADP, 10 μM glucose 1,6-bisphosphate, 10 mM MgCl2, 225 mM trehalose, 3 U/mL phosphoglucomutase and 3.4 U/mL glucose 6-phosphate dehydrogenase.

Assay II: Synthetic activity was routinely assayed at 40° C. using the following conditions: 50 mM sodium MES buffer pH 7, 100 mM aG1P and 100 or 500 mM glucose concentrations as given. Reaction progress was determined discontinuously by measuring liberated phosphate with an assay based on the complex formation with molybdate under acidic conditions. The molybdate complex is reduced by ferrous sulfate and yields a blue color, which is analyzed photometrically at 750 nm. For the analysis 250 μF of sample are mixed with 250 μL 0.5 M HCl and 500 μL molybdate-reagent (73.2 g/L Fe(II)SO4*7H2O and 10 g/F ammonium molybdate*4H2O in 3.5% sulfuric acid). After incubation at RT for 15-30 min, absorbance is measured at 750 nm. The amount of inorganic phosphate in the sample is quantified using external standards.

Example 2: Effect of Sucrose on Thermal Stability

Expression of recombinant TPs: The wild-type enzyme SEQ ID NO: 1 was expressed in shaking flasks by inoculating Medium I (4.6 g/F yeast extract, 9.3 g/F peptone, 25 mM Na2HPO4*12H2O, 25 mM KH2PO4, 50 mM NH4Cl2, Na2SO4, 5 g/F glycerol, 0.5 g/F glucose*1H2O, 2 mM MgSO4, 50 μg/mF kanamycin) with a fresh overnight culture. Cultures were induced in the logarithmic phase with 0.1 mM IPTG and expressed overnight at 24-25° C.

Preparation of TP enzyme preparations: For the preparation of cell extract without sucrose cells were harvested by centrifugation and suspended in a buffer containing 50 mM potassium phosphate-buffer pH 7, 2 mM MgCl2, 0.5 mg/mL lysozyme and 20 U/mL nuclease. Cells were disrupted by sonication. Cell free extract containing soluble enzyme was separated from the debris by centrifugation. For the preparation of cell extract with sucrose as a stabilizing agent, cells were harvested by centrifugation and suspended in a buffer containing 100 mM potassium phosphate-buffer pH 7, 2 mM MgCl2, 0.5 mg/mL lysozyme and 20 U/mL nuclease. Cells were disrupted by sonication. Cell free extract containing soluble enzyme was separated from the debris by centrifugation and diluted 1:2 with 2 M sucrose solution.

Determination of denaturation profile: 50 μL aliquots of enzyme preparations with and without 1 M sucrose were incubated for 15 min at temperatures ranging from 36 to 53.7° C. Denatured protein was separated by centrifugation. The activity of the resulting supernatants as well as cell extract without a heat inactivation step was determined using Assay I. FIG. 1 is a denaturing profile of SEQ ID NO: 1 with and without 1 M sucrose as a stabilizing agent showing the obtained residual activities compared to the enzyme preparations without heat inactivation. The addition of 1 M sucrose results in an increase of Tm50 from approx. 40° C. to 47.5° C. 1 M sucrose was therefore chosen as a stabilizing agent for TP.

Example 3: Residual Activity of TP Variants after Incubation at 52° C. for 15 Min

Expression of recombinant TPs: Recombinant TPs were expressed in deep-well plates by inoculating Medium I (4.6 g/L yeast extract, 9.3 g/L peptone, 25 mM Na2HPO4*12H2O, 25 mM KH2PO4, 50 mM NH4Cl2, Na2SO4, 5 g/L glycerol, 0.5 g/L glucose*1H2O, 2 mM MgSO4, 50 μg/mL kanamycin) with a fresh overnight culture. Cultures were grown at 37° C. up to an optical density at 600 nm of 0.6-0.8. Cultures were induced with 0.1 mM IPTG final concentration. Expression was at 24-25° C. overnight.

Preparation of TP enzyme preparations: Cells were harvested by centrifugation and suspended in 100 mM potassium phosphate-buffer pH 7, 2 mM MgCl2, 0.5 mg/mL lysozyme and 20 U/mL nuclease. Cells were disrupted by repeated freeze/thaw cycles. Cell free extract containing soluble enzyme was separated from the debris by centrifugation. The cell free extract was diluted 1:2 with 2 M sucrose solution.

Heat-inactivation and activity measurement: A 50 μL aliquot of each TP was incubated at 52° C. for 15 min. Denatured protein was separated by centrifugation. The activity of the supernatant was determined using Assay II with 500 mM glucose. Another aliquot of each TP was assayed directly for activity without heat-inactivation using Assay II with 500 mM glucose. The resulting residual activities are listed in Table 6. All variants showed a higher residual activity than the wild-type enzyme which means they possess an improved thermal stability compared to the wild-type.

The resulting 100/500-ratios are listed in Table 7. As can be seen, some variants showed, in addition to an improved thermal stability, also a higher 100/500-ratio compared to the wild-type. This is an indication for an improved Km-value for glucose.

Example 5: Denaturation Profiles of TP Variants

14 TP variants, which had shown high improvements in thermal stability in Example 3, were selected for the determination of their Tm30- and Tm50-values. Denaturation profiles were determined in 50 mM potassium phosphate buffer pH 7 containing 1 M sucrose as described in Example 2. The following Tm30- and Tm-50-values were extrapolated from the denaturation profiles:

Example 6: S/P-Ratio

The wild-type enzyme and 23 TP-variants were selected for the determination of the S/P-ratio. Cell extracts were prepared as described in Example 2. The activity was determined in the direction of trehalose phosphorolysis (Assay I) and trehalose synthesis (Assay II, 500 mM glucose). The ratio between synthesis and phosphorolysis activity (S/P-ratio) was 0.3 for the wild-type enzyme, which means that the enzyme shows higher reaction rates in the direction of trehalose cleavage. The tested TP variants all showed S/P-ratios above 0.3. SEQ ID NO: 42 and SEQ ID NO: 53 showed the highest improvements with an over 3-fold higher S/P-ratio compared to the wild-type enzyme.

Example 7: Process Stability at 45° C.

Process stability of the wild-type enzyme and the TP variants SEQ ID NO: 14, SEQ ID NO: 44, SEQ ID NO: 62, SEQ ID NO: 64, SEQ ID NO: 65 and SEQ ID NO: 78 was determined at 45° C. in 50 mM potassium phosphate buffer pH 7 containing 1M sucrose. Cell extracts were prepared as described in Example 2. Samples were incubated at 45° C. for 16 days. Samples were taken over time and the activity was measured using Assay I. The results are shown in FIG. 2. SEQ ID NO: 1 showed a rapid activity loss within the first 3 hours and a half-life of approx. 1 hour. As expected from the Tm50-values, the new variants showed greatly improved process stability. SEQ ID NO: 62, SEQ ID NO: 65 and SEQ ID NO: 78 showed the highest improvements with half-lives of approx. 8.8 days. This constitutes an over 200-fold improvement compared to the wild-type enzyme.

Example 8: Alternative TP Enzymes

A possibility to identify alternative wild-type enzymes which possess trehalose phosphorylase activity is to compare known trehalose phosphorylases to sequences deposited in sequence databases, such as GenBank. In order to identify alternative TP enzymes, SEQ ID NOT was blasted against the non-redundant database of GenBank (NCBI). Alternative trehalose phosphorylases may be chosen from database sequences which either possess high sequence similarity to SEQ ID: 1, such as the putative trehalose phosphorylase from Hypholoma sublateritium FD-334 SS-4 (GenBank accession: KJA27491.1) or functionally characterized trehalose phosphorylases such as the enzymes from Lentinus sajor-caju (Genbank accession: Q9UV63.1), Grifola frondosa (Genbank accession: 075003.1 or ADM15725.1) or Pleurotus ostreatus (Genbank accession: KDQ33172.1). The sequences of these four enzymes were aligned to SEQ ID NO: 1 in FIG. 3.

Variants of alternative wild-type trehalose phosphorylases are created using the methods described in Example 1. The variants contain one or more mutations at the positions corresponding to L114, I118, G357, P383, N225, A304, T323, S556, T564, A649 and L712 in SEQ ID NOT.

Variants are tested for improved thermal stability as described in Example 3. The heat inactivation step is carried out at the temperature at which the corresponding wild-type retains approximately 20% residual activity after incubation for 15 min. It is expected, that the new variants will show similar improvements to the variants in Example 3. Further mutations corresponding to positions L114, I118, G357, P383, N225, A304, T323, F349, Q487, V550, S556, T564, A649 and L712 in SEQ ID NO: 1 may be added. It is expected, that the addition of one or more of these mutations will lead to a further improvement in thermal stability.
